Java模拟新浪微博登陆抓取数据前言:
兄弟们来了来了，最近有人在问如何模拟新浪微博登陆抓取数据，我听后默默地抽了一口老烟，暗暗的对自己说，老汉是时候该你出场了，所以今天有时间就整理整理，浅谈一二。
首先：
要想登陆新浪微博需要预登陆，即是将账号base64加密，密码rsa加密以及请求http://login.sina.com.cn/sso/prelogin.php链接获取一些登陆需要参数，返回的接送字符串如：
"retcode":0,"servertime":1487292003,"pcid":"gz-9e1f24c9acdefb111e1c8078558c7d9c0bf2","nonce":"VHRDG1","pubkey":"EB2A38568661887FA180BDDB5CABD5F21C7BFD59C090CB2D245A87AC253062882729293E5506350508E7F9AA3BB77F4333231490F915F6D63C55FE2F08A49B353F444AD3993CACC02DB784ABBB8E42A9B1BBFFFB38BE18D78E87A0E41B9B8F73A928EE0CCEE1F6739884B9777E4FE9E88A1BBE495927AC4A799B3181D6442443","rsakv":"1330428213","is_openlock":0,"lm":1,"smsurl":"https:\\/\\/login.sina.com.cn\\/sso\\/msglogin?entry=weibo&mobile=18360903574&s=ea7a2e91c5f1d6da7f42aa87fe6963d0","showpin":0,"exectime":222
，接下来是预登陆处理代码：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 |
/**
* @author LongJin
* @description 初始登录信息<br> 返回false说明初始失败
* @return
*/
public
boolean
preLogin()
boolean
flag =
false
;
try
su =
new
String(Base64.encodeBase64(URLEncoder.encode(username,
"UTF-8"
).getBytes()));
String url =
"http://login.sina.com.cn/sso/prelogin.php?entry=weibo&rsakt=mod&checkpin=1&"
+
"client=ssologin.js(v1.4.5)&_="
+ getTimestamp();
url +=
"&su="
+ su;
String content;
content = HttpUtils.getRequest(client, url);
System.out.println(
"content------------"
+ content);
JSONObject json = JSONObject.fromObject(content);
System.out.println(json);
servertime = json.getLong(
"servertime"
);
nonce = json.getString(
"nonce"
);
rsakv = json.getString(
"rsakv"
);
pubkey = json.getString(
"pubkey"
);
flag = encodePwd();
catch
(UnsupportedEncodingException e)
System.out.println(
"抛出UnsupportedEncoding异常"
);
catch
(ClientProtocolException e)
System.out.println(
"抛出ClientProtocol异常"
);
catch
(IOException e)
System.out.println(
"抛出IO异常"
);
Python实现新浪微博登陆！验证码？反爬？在我这里是不存在的！
